Tarbert is a village in Scotland in the Argyll and Bute council area. It is built around East Loch Tarbert, an inlet of Loch Fyne, and extends over the isthmus which links the peninsula of Kintyre to Knapdale and West Loch Tarbert. Tarbert had a recorded population of 1,338 in the 2001 Census.
Tarbert has a long history both as a harbour and as a strategic point guarding access to Kintyre and the Inner Hebrides. The name Tarbert is the anglicised form of the Gaelic word tairbeart. It is composed of tar "across" and a form of the verb beir "carry" and literally translates as "across-carrying". This refers to the narrowest strip of land between two bodies of water over which goods or entire boats can be carried. In past times cargoes were discharged from vessels berthed in one loch, hauled over the isthmus to the other loch, loaded onto vessels berthed there and shipped onward, allowing seafarers to avoid the sail around the Mull of Kintyre.
Tarbert was anciently part of the Gaelic overkingdom of Dal Riata and protected by three castles — in the village centre, at the head of the West Loch, and on the south side of the East Loch. The ruin of the last of these castles—Tarbert Castle—still exists, and dominates Tarbert's skyline. Around the year 1098 Magnus Barefoot, King of Norway, had his longship carried across the isthmus at Tarbert to signify his possession of the Western Isles.
Despite its distinction as a strategic stronghold during the Middle Ages, Tarbert's socioeconomic prosperity came during the Early Modern period, as the port developed into a fishing town. At its height, the Loch Fyne herring fishery attracted hundreds of vessels to Tarbert.
All placenames that variously show up as tarbert, tarbat or tarbet in their anglicised form derive from either Irish an tairbeart in Ireland and Scottish Gaelic an tairbeart in Scotland, both commonly translated as "the isthmus" today. Both these words derive from two Old Irish elements, tar "across" and a nominalised form of the verb ber "to carry". So the literal translation would be an "across-carrying". The reason for this is that all tarberts are in fact located at or near old portage sites.
In English language spellings the first syllable "tar" has generally remained constant but the second syllable "bert" has variously been spelled as "bart", "bert" "bat", "bad" etc.
